Buy Compact Wafer Ball Valve Q71F/Q971F PN1.6–2.5MPa Stainless Steel Electric Operated
The ultra-thin wafer type ball valve from VALVEHU is engineered for compact, high-performance fluid control in pipelines with space or weight constraints. Designed under models Q71F, Q371F, and Q971F, this valve features a reliable ball mechanism, quick shut-off capabilities, and a space-saving wafer design — making it ideal for various industrial applications including chemical processing, water treatment, oil & gas, and HVAC systems.
This valve supports a pressure range of PN1.6 to 2.5 MPa, accommodating both medium and high-pressure flow environments. The body materials available are WCB (carbon steel), CF8 (304 stainless steel), and CF8M (316 stainless steel) — ensuring excellent resistance to corrosion, wear, and chemical aggression.
Internally, both the ball and stem are made of stainless steel variants such as 06Cr19Ni10 or 06Cr17Ni12Mo2, delivering robust torque performance and durability. PTFE (Polytetrafluoroethylene) is used for the seat and packing, ensuring minimal friction, excellent sealing, and chemical inertness.
Its wafer connection type makes it easy to install between flanges, reducing assembly time and maintenance efforts. Available sizes range from DN15 to DN125, and structural lengths vary between 35mm to 200mm, based on nominal diameter.
This compact ball valve is available in manual handle, gear-operated, and electric-actuated models, giving flexibility across automation levels.
If you’re looking for a reliable and compact solution to integrate into your pipeline system, this wafer-type ball valve is a strong contender.
